Short summary
We present the design and operation of a newly built continuous-flow reactor (CFR), which can be used as a tool to gain considerable insights into the composition and physical state of secondary organic aerosol (SOA). The CFR was used to generate large quantities of SOA mass, allowing the use of highly accurate techniques that are not usually accessible. We demonstrate how this unique approach can be used to investigate the relationship between SOA formation and physiochemical properties.
